Long Pond Ironworks was founded in 1766 by German ironmaster Peter Hasenclever. Hasenclever brought 500 ironworkers and their families from Germany to build an ironworks "plantation," including a furnace, forge, houses, shops, and farms. A dam at "Long Pond" (Greenwood Lake) on the upper Wanaque River provided the hydropower to operate a blast for the furnace and a large forge. Two more furnaces were constructed in the 1860s. Operations at the site ceased in 1882 due to the industry-wide conversion to anthracite furnaces using Pennsylvania coal. The remnants of the ironmaking industrial structures at this site date from the 18th and 19th centuries. Furnaces, casting house ruins, charging areas, ice houses, waterwheels, and other structures are a part of the remains. The area is currently undergoing restoration: one waterwheel has been reconstructed and several houses stabilized. The "Old Country Store" has been renovated and now houses the Long Pond Ironworks Museum. The original Village of Hewitt grew up around the 19th-century iron enterprise. This settlement included a church, a store/post office, schoolhouses, and dwellings and outbuildings for workers and managers. Many of these cultural resources remain intact or as ruins.

Bishop Hill was the site of a utopian religious community founded in 1846 by Swedish pietist Eric Janson (1808–1850) and his followers. A number of historically significant buildings have survived and are scattered throughout the village, four of which are owned by the state and managed as part of the Bishop Hill State Historic Site. The 1848 Colony Church is a two-story frame building. The three-story stuccoed-brick 1850s Colony Hotel served commercial travelers and provided a link to the outside world. The 1850 "Boys' Dormitory" is a small two-story frame structure believed to have provided housing for boys making the transition to working adulthood. An 1850s Colony barn was relocated behind the Hotel to the site of the original Hotel stable. In addition to the historic structures, the state owns the village park with a gazebo and memorials to the town's early settlers and Civil War soldiers. The brick museum building houses a valuable collection of primitivist paintings by colonist Olof Krans (1838–1916).

The site offers exhibits, a short film, and occasional recreational and educational events.

Allaire State Park houses Allaire Village, a well-preserved early 19th-century ironmaking town with a general store, blacksmith shop, carpenter's shop, owner's house, foreman's house, church, and museum.

Lincoln State Monument manages most of the historical buildings in the community of Lincoln. This most widely visited state monument in New Mexico is part of a community frozen in time—the 1870s and 1880s. The monument includes 17 structures and outbuildings, 4 of which are open year-round and 2 more seasonally as museums. Most of the buildings in the community are representative of the Territorial Style of adobe architecture in the American Southwest. Lincoln is a town made famous by one of the most violent periods in New Mexico history. Today's visitors can see the Old Lincoln County Courthouse with museum exhibits that recount the details of the Lincoln County War and the historic use of the "House" as store, residence, Masonic Lodge, courthouse, and jail. Visitors walk in the footsteps of Billy the Kid, Pat Garrett, and other famous and infamous characters of the Wild West, and trace the events of 1878 through the Courthouse and the Tunstall Store, which contains displays of the original 19th-century merchandise in the original shelving and cases. They can then continue through history by visiting the Dr. Woods House, defensive torreón (tower) for the village; the San Juan Mission Church; and the Montaño store. The Anderson-Freeman Museum features historical exhibits in a timeline starting with American Indian prehistory and ending with the Lincoln County War. A 12-minute video about the Lincoln County War and the community is shown throughout the day.

The site offers a short film, exhibits, and tours.

For the child who believes milk comes from the grocery store instead of a cow, for the woman who remembers using a cornsheller on her grandmother's farm, or the family who takes 20th-century technological advances and the farmer for granted, the Delaware Agricultural Museum and Village offers a memorable and educational experience. By preserving the quickly fading agricultural heritage of Delaware and the Delmarva Peninsula, the Museum stands as an important legacy for future generations. A main exhibit building and 15 historic structures associated with a 19th-century farming community bring the fascinating story of agriculture to life. More than 4,000 artifacts are displayed in the main exhibit building—from butter churns to threshers, from an 18th-century log house to the first broiler chicken house.
